长江流域重要生境及主要生态制约问题辨识

Identification of important habitat and major ecological restrictive problems in Yangtze River Basin

从长江流域分布的珍稀动植物栖息地、重要和特有鱼类的洄游通道、重要珍稀陆生动物的迁徙通道等生态敏感区方面,辨识提出长江流域重要陆生生境和水生生境、以及重要陆生和水生生态敏感区。在辨识自然保护区、风景名胜区、地质公园、森林公园、世界自然文化遗产、水土流失重点预防区、重点文物保护单位等重要生态与环境敏感区的基础上,结合水资源开发利用现状和规划,研究长江流域不同区域、不同河流存在的生态与环境制约因素。

By analyzing the important ecological sensitive areas in Yangtze River Basin including habitat of treasured animals and plants,migration channels of treasured fish and treasured terrestrial animals,we identify and present the sensitive areas of important terrestrial habitat,aquatic habitat,terrestrial and aquatic ecological areas.On the basis of identifying the important ecological and environmental sensitive areas,such as natural reserve,scenic spot,geological park,forest park,world natural and cultural heritage,key conservation area of soil and water erosion and key cultural relics protection unit,and combining the status and planning of water resources development,we study the existed ecological and environmental restrictive factors in different regions and rivers in Yangtze River Basin.
